Bureau of Land Management20140807BLM OR Land Tenure Zones Polygonvector digital datahttp://www.blm.gov/or/gis/data.phpLTZ_POLY: This feature class represents BLM Land Tenure Zones (LTZ) for Oregon and Washington, areas (zones) on BLM lands as Retention/Acquisition, Exchange, or Disposal of lands under BLM jurisdiction. The LTZ polygons do not identify actual acquisition or disposal actions, but rather the zones of potential land tenure adjustment as determined through the land use planning process. All BLM lands are covered by these zones. For detailed information on individual parcels contact the relevant BLM Oregon district staff. This data conforms to the 'Land Tenure Zones Spatial Data Standard 20131130. 'http://www.blm.gov/or/datamanagement/index.php'This dataset is used for depicting the different BLM Land Tenure Zones on maps and for overlaying in GIS with other data themes to determine feasibility and impact of project proposals.20140807publication dateCompleteAs needed-121.682972-116.77275346.10073341.978511BLMManagementISO 19115boundariesNoneSuitable for DisposalBLMLandsLTZZone 2Retention and AcquisitionLand Tenure ZoneZone 1Suitable for ExchangeLand Use PlanningZone 3Bureau of Land ManagementLUPISO 19115 Topic CategoriesplanningCadastreboundariesNoneOR/WAORWABLM-StateWashingtonOregonPUBLIC DATA: None, these data are considered public domain.These data are provided by Bureau of Land Management (BLM) “as is” and may contain errors or omissions.

The LUP names are a subset of the larger PLANID domain. BLMBLM_ORG_CDA combination of the BLM administrative state and field office which has administrative responsibility for the spatial entity. This includes which office covers the entity for planning purposes and which office is the lead for GIS edits. Another agency or individual may have the physical management responsibility for the on-the-ground entity. This field applies particularly when a spatial entity crosses resource area or district boundaries and the administrative responsibility is assigned to one or the other rather than splitting the spatial unit. Similarly, OR/WA BLM may have administrative responsibility over some area that is physically located in Nevada, Idaho, and California and vice versa. When appropriate, the office can be identified only to the district or state level rather than to the resource area level. The domain listing for this attribute is too lengthy to list here. Consult the data standard for this data or contact the OR BLM data steward for the domain listing.

The standard spatial reference of Geographic (NAD 1983) cannot be used for calculating acres so the features are projected to one of three projections as determined by the BLM_ORG_CD of the record. These three projections all utilize linear units of meters, so the ESRI Geodatabase-controlled field SHAPE.AREA can be used to convert to acres with the factor based on the U.S. Survey Foot: GIS_ACRES = SHAPE.AREA * 0.0002471044; District indicated by BLM_ORG_CD: ESRI Projection used: Prineville NAD 1983 USFS R6 Albers; Coos Bay, Eugene, Lakeview, Medford, Roseburg, Salem NAD 1983 UTM Zone 10N; Burns, Spokane, Vale NAD 1983 UTM Zone 11NBLMSHAPE.AREASHAPE.LENBureau of Land ManagementEric HiebenthalGIS Data Management SpecialistmailingP.O Box 2965PortlandOR97208US503-808-6340503-808-6419ehiebent@blm.govcontact instructionsThe BLM assumes no responsibility for errors or omissions.
